Abstract
Techniques and devices for integrating optical fibers on substrates with grooves for various optical applications. Two openings that penetrate through the substrate are formed at both ends of each groove to allow a fiber to pass from one side of substrate to another side. The fiber cladding of a fiber portion positioned in the groove can be removed to produce an optical coupling port.
